The control circuit controls the switching circuit to adjust a level of a current in the inductor by a first amount over a data transmission period, such that the inductor emits a magnetic pulse including a first magnitude during the data transmission period. The control circuit controls the switching circuit to adjust the level of the current in the inductor such that the level of the current is increased and decreased repeatedly by a second amount between two different levels during a data non-transmission period, and the inductor emits a magnetic pulse including a second magnitude during the data non-transmission period. The second amount is less than the first amount, the first magnitude is greater than a threshold value and the second magnitude is less than the threshold value.
